Questions on Hotronics

post #1 of 26
Thread Starter 

1. What is the best way to attach the batteries to the boot: the side strap bracket or that hardware that has to be screwed into the boot?  My old M4s with the simple wire clips just don't stay on my boots no matter how I rig them.

2.  Do the new E3 batteries last as long as advertised?  The website says they're basically equivalent to the old M4.

3.  Will my old wall charger for M4s work with E3 and E4 batteries?

4.  Has anyone tried those extension cords that snake through your ski pants, allowing you to keep the batteries in pockets?  Would be nice to get the weight off your boots but those cords could be pretty annoying snaking up your legs.

 

Thanks!

Use the booster strap clip. Keep it all short and sweet... I'd be hesitant to recommend the pocket/leg/foot route, especially since the extra weight doesn't seem to bother anyone I know who uses them, even the 110 lb'ers.

Make sure you get the newest version of the clips...I lost one of my batteries with the older model. Very easy for them to get knocked off while getting off lifts or just normal skiing/walking. Newer model almost locks battery into place.

Never heard of the weight of the batteries being an issue on the boot and I would not want to have the batteries sitting in my pants pockets. Also never heard of anyone screwing hardware into the boot for the battery. Just clips onto the power strap.

I did on my old Tecnica Diablos.  There really wasn't any other option because my ski pants would not fit over the battery when it was clipped to the booster strap.  But I don't need the heaters since I discovered Intuition liners.

I drilled the mounts on my old Tecnicas.

They didn't last too long--the wires were a problem. Be careful loading chairs, etc. Mine were fun while they lasted. I mounted mine to the outside, but aggressive skiing and mindless loading destroyed the cords.

They need a better system for batteries not getting lost...especially at these prices!
post #7 of 26

I've had both and prefer to just hang them on my booster straps.  Some pants don't accommodate the batteries very well.

A related question: any ideas on keeping the battery packs on when there is no strap? My son has these boots and the batteries are clipped onto the back, but that isn't working ... he has knocked them off repeatedly and is lucky to have not lost one yet. I think I'm going to use duct tape today b/c he is going skiing for the weekend so we need to do something today. I hear there are mounts that you can drill into the boot, but I haven't found them yet.

I hook mine on the tongue pull strap and then make sure powder cuff on pants goes over them so if the clip comes off at least they stay in cuff....

There are some brackets that Therm-ic sells (and still available on EBay) that screw on to the boot. Not sure if they'll fit on the Hotronics. I have some hanging around so if you send me an address you can try them out.

post #11 of 26

Yeah, I should have said I can't find them in person. I can certainly order them, and will have to do that.

Thanks for the replies.  Clearly the weaknesses in this technology are 1. how they attach to the boot and 2. the durability of the cords.

Segbrown - you might try Lee at Custom Foot - he installs heaters and might have what you need. I'm setting up an appt myself...but that's for the entire setup not just mounting.

I've done it all, they are very frustrating to me.  Batteries go bad, wires go bad, etc.

 

The clips that attach to the booster or power strap were my favorite way, but in order to pull my boosters tight enough there's now no room for them, so I've gone back to using the standard clips and putting them in the back.  They seem to hold pretty well - I do put my powder cuff over the batteries so if they come off they'll stay in my pants - theoretically.

 

I talked to Hotronics recently for a warranty replacement (they go back three years and didn't need a receipt.)  They told me the new batteries work on the M4 charger.  They also told me they got a little warmer than the M4's and last a little longer.

 

I have a drawer full of extra parts, old batteries, old clips.  I did do the screw it on to your boots method once which worked well.

I have some of the Hotronic clips.  You can have them when you come to JH.  I hook mine onto the powerstrap.  You could probably hook onto the shell somehow.

Thanks .. .we actually have an extra pair of clips, I just couldn't figure out how to get them on the shell. I ordered some mounting brackets earlier, so we will just drill a hole and do it that way.

This is my second season with Hotronics e4s.  The are mounted to my powerstrap on the side and I've never had a problem.  Most of my pant gaiters go over them (some more easily than others).  Now, when I buy new pants, I bring my boots and batteries to make sure the gaiters accommodate the extra bulk. They've never been knocked off on a lift or in deep powder or during a fall.  My wires are still good and the batteries seem to last all day (9am to 4pm). I'm not a big person (5'5", 120lbs) and I don't even notice they are there.

 

You may notice that it looks like the toes of my liners are covered in tin foil.  It's actually aluminum duct tape.  It's an experiment my boot fitter and I are doing to see if we can keep the heat from escaping.  I tested the concept with one boot on Saturday and felt like that foot was, in fact, a bit warmer.  So, today, he taped up the other.  It's a little ghetto but it seems help.  I have Reynaud's and my feet are never warm.

SLC: aluminum tape in addition to Hotronics? How much warmer?

The jury is still out on that. The day I tried it on the right foot only, we had a high of 35F.  But I felt like it did make a difference...as if the heat stayed trapped in my liner a little better.  Did I mention he completely covered the bottom of the liner (sole of the foot) with the aluminum tape as well?  It's not just on the toes.  I will report back the next time we have a really cold day, like the -22F we had on Sunday, and let you know.

 

I also have had BootGloves for 3 seasons but I feel like trashing them.  All they seem to do is trap snow between the neoprene and my boot.  Essentially, packing my foot in ice!  What a stupid invention.

I have run into a few problem with Hotronics e4 mounting and I have found a solution. The strap attachment works great but I prefer them on the back of the boot. Of course the issue arises where the chair lift can do damage and knock the pack off its mount. I used to mount them to the clip screwed into the back of the boot with the wire clip but I lost a pack that way. A $76 loss and lesson learned.  

 

What I have done now is to remove the black write holder and wire from the pack. then run a piece of frame hanging wire through one of the the holes on the pack and then around the old clip thats still attached to the boot acting as a safety cable. Then replace the black wire holder back into the pack. Put two strips of 3M 1" VHB double sided foam achrylic tape over each other and a along the length of the black strip and spine of the pack. I use two strips back to back to build up the concave area so it meshes better with the boot spine. Attach it to the spine of the boot and apply force to make a tight bond. The tape will hold but it takes about 72 hours to fully bond 100%. With additional pieces of tape, run them along the inside of the boot and the pack.

 

If you haven't used or heard of VHB Tape its unbelievably strong. Its used in industrial construction as well amounting things like GoPro cameras to helmets. After about 72 hours it bonds to 100%. It will hold 100lb's per inch. I have had this on my bo\ots for a couple of weeks now with no issues. The tape is tested in all kinds of weather and envioremts as you can see by the video... Good Luck!

 

Usually this isn't something you can buy at Home Depot or Lowes. Its very strong. Check out the video from the History Channel below.

Bump.

 

I'm looking for a way to get a more durable mount. I bought the powerstrap mount and clipped them to the side of the boot. The today I lost them after falling and breaking the bracket. I didn't notice until the end of the day so that is money down the drain. I have not had good luck with the durability of the E4. Not a happy camper.

After years of frustration I sold all my hotronic batteries, elements and mounts on ebay and bought a case of toasty toes.  I can fit one on top of my foot (yes my boots are VERY tight, but they still fit.)

 

Never have to worry about broken wires, lost batteries, bad batteries, bad elements again.

 

Also some duct tape across the overlap of the boot shell above my toes made a huge difference in my foot warmth.

I do toasty toes and hotronics.  Toast toes over the toes and under the heel.  Hotronics under the toes of course.  It was just barely adequate this winter.  I have very cold feet.

Try Sidas - the battery packs look to be about half the size of Hotronics. Those things are huge.
post #25 of 26

I used the holes in my boots where the power straps were attached, and attached hotronic mounts there. Mounts attached and no new holes in my boots. I also turned the battery a little to the outside so that the cable comes off the top of the battery off to the outside of the boot so I don't catch them on the lifts and break the connectors.

 

I have found that the new clips don't release very easy.. It' a bear to remove the batteries from my boots so I just leave them there and charge them in place..

post #26 of 26

I could never find a decent mounting point for the fancy clips.  I just hook the batteries over my Booster Strap right behind the buckles using the stock wire clip.  Then I pull the powder cuff over the whole thing.  I have never lost a battery or had any problems with lifts or stairs.
